摘要
以单片机STC89C51和数字温度传感器DS18B20为核心,设计了利用数字温度传感器检测室内外温度的装置。针对温度分布不均的特点,解决了传统单个测温传感器难以准确获得温度信息的问题。采用STC89C51单片机控制,可设置上下报警温度,当温度超过设置范围内时,可以报警。该测温系统具有操作简单、效果稳定、精度高等优点,可应用于多种实际场合。
With microcontroller STC89C51 and digital temperature sensor DS18B20 as the core, using digital temperature sensor to design the testing device for indoor and outdoor temperature. According to the characteristics of temperature distribution, solving the traditional single temperature sensor difficult to accurately obtain the temperature information. Adopt STC89C51 microcontroUer to control, which can be set up alarm temperature. When the temperature exceeds set range, it can alarm. The temperature measurement system has the advantages of simple operation, stable effect and high precision ,which can be applied to a variety of actual situations.
